apparent propagation of the equine infectious anemia virus in a mosquito (culex pipiens quinquefasciatus say) ovarian cell line.a tissue culture of culex pipiens quinquefasciatus say ovarian cells appeared to support the growth of equine infectious anemia (eia) virus. shetland ponies inoculated with 2nd, 7th, 9th, and 11th passages of mediums harvested from infected tissue culture had clinical signs of the disease and became eia positive on 11, 19, 23, and 43 days after inoculation, respectively.1976183574
purification and characterization of equine infectious anemia virus.eia virus was purified from equine fetal kidney cell cultures by peg-precipitation, two sucrose-gradient sedimentations (5-30 per cent) and (25 to 60 per cent) centrifugation, using the immunodiffusion test to follow the procedure. purified eia virus had a density (20 degrees c) of 1.162 and a sedimentation constant of s20w=656. electron microscopy revealed a particle of about 100 nm in diameter with a very flexible but usually spherical shape. the dense core may be at various locations inside t ...1976183628
transmission of equine infectious anemia virus by tabanus fuscicostatus.the mechanical transmission of equine infectious anemia (eia) virus by tabanus fuscicostatus was investigated. in 1 of 7 transmission trials, a single horsefly transmitted eia virus from an acutely infected pony to a susceptible pony. groups of horseflies isolated for 3, 10, or 30 minutes before refeeding transmitted eia virus, whereas those isolated for 4 or 24 hours did not. data from field studies indicate that the home range or flight distance of horseflies may exceed 4 miles. that informati ...1976942712
equine infectious anemia virus: evidence favoring classification as a retravirus.equine infectious anemia virus (eiav) has a density of 1.154 g/cm3 in sucrose a high-molecular-weight rna similar in size to rauscher murine leukemia virus, and an internal virion reverse transcriptase that utilizes the synthetic rna template poly(ra) but not the synthetic dna template poly(da), both with (dt)12 as primer. although capable of utilizing manganese at low concentrations (approximately 0.1 mm), eiav reverse transcriptase showed highest activity in the presence of 9 mm magnesium. the ...197661283
hemagglutination by equine infectious anemia virus.equine infectious anemia (eia) virus which was propagated on an equine dermal cell line agglutinated guinea pig erythrocytes. viral fluids containing about 10(7.5) mean tissue culture infective doses/ml showed hemagglutinating (ha) titers ranging from 16 to 32 units/0.05 ml. results of cesium chloride equilibrium density gradient centrifugation revealed that the hemagglutinin was inseparable from the virus particles. the hemagglutination reaction persisted over a wide range of temperature and ph ...19769361
rna-dependent dna polymerase associated with equine infectious anemia virus.equine infectious anemia (eiav) is shown to have an associated rna-instructed dna polymerase similar in its cofactor requirements and reaction conditions to the rna tumor virus dna polymerases. demonstrating this dna polymerase activity requires a critical concentration of a nonionic detergent, all four deoxyribonucleoside triphosphates, and a divalent metal ion. the reaction is sensitive to rnase, and a substantial fraction of the fna synthesized is complementary to viral rna. the detection of ...197767219
purification of equine infectious anemia virus antigen by affinity chromatography.affinity chromatography was performed to obtain highly purified antigen from equine infectious anemia (eia) virus. after crude antigen was concentrated by polyethylene glycol precipitation of culture fluids from equine dermal cells persistently infected with eia virus, and after the virus was disrupted with ether, it was added to a column of cyanogen bromide-activated sepharose 4b to which eia-specific antibody had been conjugated. the antigen was effectively released from the column with 5m mgc ...197769631
characterization of a retravirus isolated from squirrel monkeys.a new retravirus (smrv) isolated from a squirrel monkey, saimiri sciureus, has an mg2+-dependen reverse transcriptase and a buoyant density of 1.17 g/cm3 in sucrose and 1.21 g/cm3 in cesium chloride, similar to the mouse mammary tumor virus and the mason-pfizer monkey virus. the polypeptide patter of smrv as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis was distinct from the reported polypeptide patterns of known retraviruses. four major polypeptides of molecular weight ...197769728
